About
An ultra-compact active DAC dongle on the Cirrus Logic CS43131, notable for native UAC1.0 (USB Audio Class 1.0) support — a legacy protocol required by game consoles that don't recognize the modern UAC2.0 standard. FiiO has shipped firmware updates (e.g. V0.08) specifically to fix volume-curve and mono-output bugs in the pre-amp stage.
Ports: 1× 3.5mm audio jack and 1× USB-C
Confirmed with
- Notebook (generic)
Confirmed used with MacBook and Windows laptops (Lenovo), but with a documented negative finding: the volume randomly drops then recovers on Lenovo laptops specifically due to a conflict with the bundled Nahimic audio middleware — reinstalling Realtek drivers is the reported workaround. No physical volume control; relies entirely on the OS mixer.
